AUTOMATIC FU R-SCALE.

SPECIFICATION forming part of Letters Patent N o. 664,619, datedDecember 25, 1900.

Application lled August Z4, 1900. Serial No. 27,937y (No model.)

To all whom/ it may concern,.-

Be it known that I, EDWARD BRENTON BOGGS, a citizen of the UnitedStates, residing at New York, in the county of New York, State of NewYork, have invented certain new and useful Improvements in AutomaticFur-Scales, of which the following is a description, reference being hadto the accompanying drawings and to the letters of reference markedthereon.

My invention relates to scales for weighing definite quantities ofmaterial so arranged that upon the deposit in the scale pan or hopper ofthe required quantity the scale pan or hopper is automatically caused todischarge its load.

My invention is particularly designed to be used in connection with ahat-forming machine to weigh the amount of fur required for each hat;and it consists in the construction and arrangement hereinafterdescribed and claimed by which this purpose is carried out.

In the accompanying drawings, which form a part of this specification,Figure 1 is a perspective view of my improved scale. Fig. 2 is a detailView showing the contact-points and mercury-cup, on an enlarged scale.Fig. 3 is a detail View showing the latch and releasing-magnet, on anenlarged scale; and Eig. 4 is a plan View.

Referring to the drawings, A is the scalebeam, having the arms A, A3,and A3. The scale-beam is pivotally supported at B' B by upright postsB, extending upward from the base C, as shown, the pivots being carriedby the arms A2 and A3.

The arm A of the scale-beam is graduated and on it is movably supportedthe poise M. At the outer end of the arm A' is hung the weight A4. Thetravel of the beam is limited by the tip-loop D, extending upward fromthe base C. Between the arms A2 and A3 extend the cross-rods a and Ct'.Within the inclosu re formed by these cross-rods and the arms A3 and A3is pivotedly supported from the arms a scale pan or hopper E. This scalepan or hopper has a swinging bottom E', carried by rods E3, providedwith pivots G, supported in brackets F, carried by the hopper. On theouter ends of the rods E3are adjustably se- `the pivots Gis placed apivoted catch I, ar-

ranged to catch and hold the bottom in place when it is thrown upwardinto place by the weights H.

In order to withdraw the catch I, so as to permit the bottom of thehopper to drop to discharge the contents of the hopper, I pro- 6o videan electromagnet J, so placed that when a current of electricity ispassed through its coilsit will attract the cat-ch I, this catch beingmade of magnetic metal, and draw it away from engagement with the edgeof the bottom.

J represents wires leading to the magnet .I from binding-screws J3,carried by the crossrod al and secured to the ends of wires which extendalong the arm and to a point in rear of the pivots and thence extenddownward to 7o the base O, where they are secured to binding-posts L L,with which a battery (not shown) is connected. One of these wires may becontinuous, but the otheris broken at a point near the outer end of thearm A3 and 75 is provided with contact-points K K, which are spaced ashort distance apart and extend downwardly. On the side of the scale panor hopper E, a short distance below the contactpoints K when the scalepan or hopper is in 8o normal elevated position, is arranged amercury-cup K, adapted to receive the contactpoints K when the scale panor hopper is depressed.

The scale pan or hopper being pivoted, as shown, near its upper edgewill always maintain a substantially perpendicular position, and so longas the weight of the material in the scale pan or hopper is notsufficient to overbalance the poise and weight at the other 9o end ofthe scale-beam the arms A2 and A3 will remain substantially horizontaland the contacts K will be above themercury-cup K. As soon as the weightin the scale pan or hopper overbalances the poise and weight thescalepan will descend, and the outer ends of the arms A2 and A3, turningon the pivots B', will drop below the horizontal and will bring thecontacts K into the mercury-cup K', closing contact through the wiresand permitting a loo current to pass through the coils of the magnet J,causing it to Withdraw the catch I and permit the bottom of thescale-pan to drop and the material in the scalepan to be discharged. Assoomas the scale-pan is empty it will be raised to normal position bythe weight and poise at the rear end of the scale-beam,the oontacts Kwill be raised out of the mercury-cup, and the bottom of the scale panor hopper will be returned to position bythe weights H and will be heldin closed position by the catch I. The operation may then be repeated.

P P are leveling-screws for leveling the base of the scale.

O O are stops carried by the scale pan or hopper in the path of movementof the arm A3 for the purpose of preventing too great movement of thescale pan relative to the scale-beam.

While I have described my invention as par; ticularly adapted toWeighing fur for hats, it is evident that it is adapted for Weighing anyother substance.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent, is-

l. The combination with a scale-beam, of a scale pan or hopper pivotallysupported by the scale-beam and having a hinged bottom, a latch forholding said bottom in closed position, an eleotromagnet carried by thescale pan or hopper for releasing the latch, a normally open electriccircuit, contact-points car- .ried by the beam and means carried by thescale pan or hopper for closing said circuit, substantially asdescribed.

2. The combination with a scale-beam, of a scale pan or hopper pivotallysupported by the scale-beam and having a hinged bottom, a latch forholding said bottom in closed position, an electromagnet carried by thescale pan or hopper for vreleasing the latch, a normally open electriccircuit, contact-points carried by the beam, and a mercury-cup carriedby the scale pan or hopper adapted to receive said contact-points andclose the oircuits when the beam is depressed, substantially asdescribed.

3. rlhe combination With a base, having the posts B and a scale-beamhaving the arms A2 and A3 and the graduated arm A pivotally supported onsaid parts, of a scale pan or hopper pivotally supported by the arms A2A3 and having a swinging bottom, a catch cal'- ried by the scale pan orhopper for retaining the bottom in place, an electromagnet carried bythe scale pan or hopper for releasing said catch, a normally opencircuit, contact-points carried by the scale-beam and means carried bythe scale pan or hopper for closing said circuit to actuate theelectromagnet, su bstantially as described.

In testimony whereof I afx my signature in presence of two witnesses.
